Substance use is not just a public health crisis, it can also be an Ophthalmic emergency. 👁️
In a Massachusetts Eye and Ear retrospective cohort study published in Ophthalmology Retina, outcomes in patients with injection drug use–associated endogenous endophthalmitis were studied.
Key findings from 62 patients:
🔎 Fentanyl use was associated with a >5x increased risk of severe vision loss
💊 Most eyes received tap-and-inject antibiotics, yet nearly half required vitrectomy
⚠️ 23% developed retinal detachment
📈 Encouragingly, two-thirds of eyes experienced vision improvement
But here is the critical point:
Only patients who saw addiction consult services (68.5%) received life-saving medication for opioid use disorder.
The takeaway? Substance use disorder carries cross-diagnostic risks—including blindness. Integrated, collaborative care between Optometry, Ophthalmology and Addiction Medicine is essential.
